IMPROVEMENT m BASE-BURNING- s'ro'vns.

The Schedule referred to in these Letters Patent and making part. of thesame.

To all whom it may concern Be it known that I,W1LLIs S. Bnoizson, of thecity and county of Hartford, and State of Connecticut, have inventedcertain new and useful Improvements in Base- Burning Hot-Air Furnaces;and

To enable others skilled in the art to make and use the same, I willproceed to describe its construction and operation, referring to thedrawings, in which the same letters indicate like parts in each of thefigures.

' This invention relates to the construction and arrangement of a seriesof circularhorizoutal smokeconducting and heat-radiating chambers orfines, 1ocated above the combustion-chamber.and around the fuel-magazineof a base-burning furnace, as now in common use. v

In the accompanying drawings Figure 1 is a side elevation.

Figure 2 is a top view of the same.

Figure 3- shows one of the horizontal fines detached,

and broken away so as to clearly show the partition.

arranged therein, as hereinafter described. The base or lower portion ofthe furnace, below the line a, is constructed much like those nowin-use.

l) is a fnel-magazinc, elevated above the c'olnbnstion-chamber. I

c is a feed-box, which enters and is secured near the upper end of thefuel-magazine. (I is a horizontal circulating-flue, arranged directlyover the top plate c of the combustion-chamber, having conducting-tubes,f, through which the smoke and heat pass into the fines.

d d are horizontal fines, arranged one above-the other, and in numbermore or less, as may be desirable. These flues are partitioned crosswisethepassagc,'so that the heat and smoke shall enter the flue from theunderside, near one side of said partition, and make its entire circuitto the egress on the upper side, and near the opposite side of thepartition.

These partitions arranged in the fines are changed alternately from oneside of the ingress-tubes, or fineopenings, which connect, and throughwhich the smoke and heat 'pass'from one to the other of the horizontalflne's, so as to alternately change the current ofheat and smoke fromone direction in one flue to the opposite direction in a succeedingflue, and thence through the pipe h, over the top of thefnel-magazine band fines or radiators 01, into the main or directdraught pipe h, orchimney. p

This direct draught h,-fromthe fire-chamber into the chimney orconducting-pipe h, when combined with the fine-draught, or the-draughtupward through the radiators (I, is designed to produce a more equal andperfectconibnstion and radiationof heat.

. i is. an air-passage, arranged upon the cover or top plate ofthecombustion-chamber, thence into the space between the double wall ofthe lowerportion of the fuel magazine, thus more efi'ectually expendingthe heat, or allowing it to be absorbed by air circulating around thefines in its passage through the furnace to the various apartments.

V This furnace and its radiating-fines (Z are designed to be enclosed inmetal or masonry, in order to form air-circulating space, as inthecommon way.

I have thus endeavored to show the nature, con struction and advantageof this invention, so as to enable others skilled in the art to make anduse the same therefrom. k

Vhat I claim, and desire to secure by Letters Patent is 1 Thehorizontal' radiating-fines (l d d, more or less in number, constructedsubstantially as described, in combination with a fuel-magazine, b,air-passage a, and conducting-tubes f, substantially as set forth.

2. The combination of the system of horizontal radiating-fines d, d, andd, and pipe 71, with adirect-diaught pipeJz-miranged to operatesubstantially as set forth.
